Passing Vlan frames through a router (ip telephony)?

Question

Telephony

Good day!
It is given:
1) There is an external network in which ip telephony functions, the frames of which are tagged;
2) There is an input router, Asus RT-AC66U, on which it is clearly not clear how to configure so that tagged frames go to the local network. However, the router implies setting up IPTV;
(You can feel the router here at random )
3) The network has a switch on which you can configure redirection of tagged frames to the desired ports.
Question
Will IP telephony work if:
1) If you set the iptv parameters like this

Will frames with VID 66 be transferred to the 3rd port?
2) Is it possible to make tagged frames go with the rest of the traffic to the switch?

I would be glad for any advice on the topic!
If I'm wrong, then at least tell me where to dig?
If there is not enough information, I can provide more.

Answer 1

If suddenly someone encounters, it turned out to solve the problem like this:
1) on the router
Local network -> IPTV-> manual
Internet and left port 4 empty, entered the vlan tag into port 3.
It turned out that the Internet goes on 1,2 and 4 ports. Tagged frames through the 3rd port.
2) I threw two cords from 3 and 4 ports of the router onto the switch. Configured on the vlan switch.
Profit.
